This study implements ways in which this data can be analyzed to produce meaningful and organized reports; these reports can be used to enhance the accuracy and efficiency of elections. Our study has been integrated into a public website intended for election officials. Results Problem Electronic voting machines generate large audit logs containing an immense amount of data. • What analyses are possible from the given data? • Can these analyses be made easily available to election officials and interested third parties? Our Contribution We analyze audit logs from the South Carolina 2010 elections to find: Analyses • Inaccuracies in election-tally reporting • Procedural errors that occurred on election day • Equipment that may need servicing • Inefficiencies at polling locations that could be averted in future elections Our Tool: AuditBear We developed several analyses and incorporated them into a web-based tool. Auditing DRE log files in a systematic way can promote accurate post-election audits. Our tool standardizes this process in the ES&S client base. • Recommendations • Recommendations to make audit files more usable: • There should be more detailed event descriptions available. • Event logs should contain accurate date and time logging. • Additional events should be used for important actions.
